The appalling penis injuries so bad they needed hospital treatment have been revealed.

From cringeworthy stunts like sliding down a flagpole to accidents like lacerating a testicle while changing a tyre, new figures show almost 3,000 men in America were admitted to hospital with such injuries in 2017.

One patient trapped their genitalia between two wheelbarrows, while another fell off the loo and on to a mousetrap which snapped shut on his nether regions.

All the incidents listed on the US Consumer Product Safety database were recorded because they had to be treated by medical staff.
